LOCKING DEVICE FOR WINDOWS, TRANSOMS, OR THE LIKE.

Specification of Letters Patent.

Patented May 17, 1910.

Application filed October 1, 1909. Serial No. 520,478.

T 0 all whom it may concern:

Be it known that I, ELLsWoRrHE. FLORA, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Locking Devices for Windows,Transoms, or the Like, of which the following is a specification.

My object is to provide a simple form of locking device for windows,transoms, and the like, and, more particularly, for the former, whichshall be economical to manufacture, permit of the securing of thewindow, transom, or the like, in any desired position, and in its use,in connection with a window or other sectional closure, permit of thelooking against tampering from the outside of the two parts thereof inany desired relative position for maintaining the window or otherclosure locked while in either completely closed or partially opencondition.

Referring to the accompanying drawingsFigure 1 is a face view of awindowcasing equipped with a double-sash window to which my improvedlocking device is applied, the full line representation illustrating thesashes as closed, and my improved locking device in position for lockingthem in this condition; and the dotted representation showing the uppersash lowered for ventilation and the two sashes locked together. Fig. 2is a View like Fig. 1 showing the locking device in non-operativeposition and the lower sash of the window slightly raised. Fig. 3 is anenlarged broken view of the middle portions of the upper crossmembers ofthe upper and lower sashes with my locking device applied thereto. Fig.4 is a section taken at the line 4 on Fig. 3 and viewed in the directionof the arrow. Fig. 5 is a section taken at the line 5 on Fig. 3 andviewed in the direction of the arrow; and Fig. 6, a section taken at theline 6 on Fig. 3 and viewed in the direction of the arrow.

I have chosen to illustrate my invention as applied to a window, thecasing 7 of which contains the vertically movable upper and lower sashes8 and 9, respectively, as is com mon in window constructions.

My improved locking device for locking the sash in either open or closedcondition as desired, comprises a rod 10 preferably supported, on theinside of the window at its eye-equipped end 11, on a rearwardlyextending hook 12 carried by an angle plate 13 secured to the uppercross-member 14 of the sash 8 intermediate the ends of the latter, as byscrews 15, as illustrated in Fig. 4, and means on the upper cross-member16 of the sash 9 cooperating with the rod 10 for locking the sashestogether.

The locking means referred to preferably comprise a bearing-head 17secured, as by screws 18, to the cross-member 16 in line with the hook12 and adapted to receive the lower end of the rod 10, and an eccentricmanually-operated clamping member 19 cooperating with said head forclamping the rod, at its lower end, in adjusted position. The headcontains a recess 20 of semicircular shape in horizontal cross-section,as clearly represented in Fig. 6, and is slotted vertically andhorizontally as indicated at 21 and 22, respectively, (Figs. 5 and 6),the rear walls of the slots 21 being preferably curved as represented at23 of the one illustrated in Fig. 5.

The eccentric clamping member 19 is in the form of a circular disk 24which contains a radial slot 25 having a semicircular end wall, asrepresented at 26, eccentric with relation to its outer curved surface,and carries a finger-grip 27, which extends through the slot 22. Theclamping member 19 is confined in the recess 20 between the curved innerwall of the latter and the face of the sash-member 16 (Fig. 6) andoperates at its outer curved surface, when rotated in the head 17through the medium of the grip 27, against the curved wall of the recess20.

WVhen the sashes have been adjusted with relation to each other asdesired to either render the window closed or open to the desireddegree, the operator introduces the lower end of the rod 10 laterallyinto the clamping device by seating it in the recess 25 in the member 19and the slots 21 in the head 17, the member 19 having been previouslypositioned as illustrated in Fig. 2, to cause its recess to registerwith the slots 21. The operator may then rotate the disk 24 from theposition represented by dotted lines in Fig. 6 to the positionrepresented by full lines therein, the member 24 in this operationmoving at its outer curved surface against the inner curved surface ofthe From the foregoing, it will be manifest that the sashes may belocked together when in position for closing the window, or whenadjusted in the casing to render the window open to any desired degree,as for ventilating, the rod 10, when clamped to the lower sash asdescribed, serving to fasten both sashes together and prevent them frombe ing moved independently of each other.

It will also be noted that the locking means for the lower end of therod are located at a point inaccessible from the out side of the windowand thus tampering with the lock is prevented.

WVhen desired, the rod 10 may be disengaged from the clamping means andswung upon the hook into any desired position, as for instance thatrepresented in Fig. 2, in which it rests upon the upper surface of thelower cross-member of the sash 9, or it may be entirely removed from thewindow by disconnecting it from the hook.

While I have illustrated and described my improved locking device asapplied to a window, I do not wlsh to be understood as limiting it tosuch use, as it may be employed in connection with any closure formed ofsections, or in connection with transoms or the like, in the latter caseits adjustable feature permitting of the securing of the transom in thedesired open or closed condition.

What I claim as new, and desire to secure by Letters Patent, is

1. A clamping device comprising a recessed head containing an openingfor a rod, and a rotatable member ournaled in the recess in said headand containing an eccentric rod-receiving opening, for the purpose setforth.

2. A clamping device comprising a recessed head containing a laterallyopening vertical rod-receiving slot in its wall, and a rotatable memberjournaled in the recess in said head and containing a laterally openingeccentric rod-receiving slot, for the pur pose set forth.

3. A clamping device comprising a recessed head containing an openingfor a rod, and a horizontally-disposed slot in its wall, a rotatablemember journaled in the recess in said head and containing an eccentricrodreceiving opening, and a finger-grip secured to said member andextending through said slot, for the purpose set forth.

4.. A clamping device comprising a recessed head containing in its walla vertical and a horizontal slot, a rotatable member journaled in therecess in said head and con taining a radial eccentrically disposed slotadapted, when said member is in one position, to register with thevertical slot in said head, and a finger-grip connected with said memberand extending through said horizontal slot, for the purpose set forth.
